Chemfallow Weed Control Limits Loss of Moisture and Nutrients
Fallowing practices have long been a part of Western Canadian agriculture, especially in areas where soil moisture levels don’t support continuous cropping. Chemfallow helps save moisture, nutrients and soil quality, as well as fuel, labour and equipment costs.
Scout often, spray less
Multiple herbicide applications may be needed to keep weeds from growing in fallow fields. Scouting fields often and timing spray applications to control weeds before they appear as green patches above stubble residue, leads to best control and limits the loss of moisture and nutrients.
Any weed is best controlled at an early stage. But you’ll have to weigh the number of times you want to be in the field against spraying at the optimum weed staging. The best timing is often at the same time or just shortly after in-crop spraying. If you wait too long to control winter annual weeds, they may require twice the amount of glyphosate.
Use Express® or PrecisionPac® brands for more effective, consistent control
A better option is to use PrecisionPac® DB-858, plus 2,4-D ester, which was designed specifically for chemfallow use. This tank-mix delivers cost-effective control of a broad spectrum of weeds including Group 2-resistant kochia, flixweed, stinkweed, Russian thistle, wild buckwheat and narrow-leaved hawk’s-beard.
If you do plan to use glyphosate, be sure to add Express® SG, Express® PRO, PrecisionPac® NC-0050 or PrecisionPac® NC-00439 to enhance the activity. Systemic herbicides such as these provide more effective and consistent control than strictly contact products because they go deep into the root instead of just burning off the top of the weed. The results may appear more slowly, but the control is much more thorough. In any case, spray before flowering to prevent seed production.
You can clean up kochia quickly by spraying out-of-crop to prevent seed production.
